PM6681ATR is a dual step-down controller specifically designed to provide extremely high-efficiency conversion, with a lossless current sensing technique. The constant on-time architecture assures fast load transient response and the embedded voltage feed-forward provides nearly constant switching frequency operation. An embedded integrator control loop compensates for the DC voltage error due to the output ripple. The pulse-skipping technique increases efficiency at a very light load. Moreover, a minimum switching frequency of 33 kHz is selectable to avoid audio noise issues.
